Urbanization leveraging domestic titanium dioxide market is expected to pick up


SMM News: Third Plenary Session of eighteen comprehensive deepening reform and made strategic plan, put forward the strong support of the new urbanization and so on. Many people in the industry said that urbanization is expected to leveraging domestic titanium dioxide market rebound.
For a long time, China has been in the field of application of titanium dioxide coatings, plastics and paper industry mainly three, which accounted for more than 60% of the paint industry. Weak demand for medical titanium plate dioxide market this year, continuing weakness, even in the "Golden September and Silver October," the traditional peak season for a "busy season" phenomenon.
China Coating Industry Association, Branch Secretary Guo Xinrong titanium dioxide industry today to the great wisdom news agency said urbanization will give China titanium dioxide industry, large enterprises to provide an unprecedented opportunity.
Industry pundits had pointed out that the country promoting the new urbanization
construction and long-term policy for the long-term prosperity and development of titanium dioxide industry to provide a strong support.
Billions have recently said that after the Third Plenary Session of China-eighth, the economic reform measures next year will gradually be implemented at the end of the two sessions, the national real estate regulation will also make greater use of market-based instruments, as well as China's urbanization affordable housing construction will also stimulate rapid and accelerating growth of domestic titanium sheet metal dioxide market.
"Real estate is an important consumer market, paint products, and urbanization will promote the real estate, infrastructure construction and renovation." Social business analyst Yang Xun told dioxide great wisdom, Chinese titanium dioxide is mainly used in the coatings industry, with accelerate the urbanization process, titanium dioxide industry will usher in a new development opportunities.
At present, the majority of mainstream offer domestic sulfuric acid rutile and anatase titanium dioxide in 13200-14500 yuan / ton and 11300-12500 yuan / ton (all taxes included).

Titanium dioxide industry standards to improve access to corporate mergers and acquisitions will accelerate


SMM News: Great Wisdom AAStocks Newswires November 13 hearing, China Coating Industry Association, Branch Secretary Guo Xinrong titanium dioxide industry on the 12th on the "titanium dioxide industry access" (revised edition) annotation and explanation, saying " access "concept by" threshold type "binding regulatory function to enhance the" screening "type guide the evaluation function. Analysis of the industry, after the access conditions improve, will promote the pace of corporate mergers and acquisitions titanium wire manufacturers dioxide.

China Coating Industry Association, SUN Lian-ying for great wisdom agency reports, the current Chinese titanium dioxide is facing many problems, there are still a lot of product structure unreasonable, companies should be how to transition, how restructuring efforts.

** Industry issues highlighted structural surplus, enterprises operating and profit situation is not optimistic **

It is reported that at present China has more than 50 manufacturers of titanium dioxide, are distributed throughout the country, including a large number of small and medium enterprises focused on the lack of resources in the eastern region. And our resources are mainly concentrated in the perovskite Southwest, the nation's largest manufacturer of titanium sheet suppliers dioxide, Sichuan Lomon current production capacity is only 300,000 tons, 100,000 tons more than the domestic producers of titanium dioxide is only nine, the whole industry is still in a relatively decentralized development period.

China Coating Industry Association branch chairman 谢湘云 titanium dioxide industry, said at the meeting that this year, the slow growth of domestic demand for titanium dioxide, titanium dioxide production capacity continues to grow, a larger increase in imports, the structural problem of excess increasingly prominent; Meanwhile, titanium dioxide Overall prices in the down channel, the current price of titanium dioxide compared with earlier this year has fallen by 15%.

In addition, the domestic titanium dioxide enterprises operating conditions and profitability are not optimistic. Xiexiang Yun said, according to statistics, this year the domestic titanium dioxide enterprises operating rate of about 66% capacity utilization rate of 95% titanium business, slag enterprises operating rate of about 35 percent, this year there are more than 20% of earnings, other titanium dioxide enterprises are operating very difficult.

On the other hand, titanium dioxide industry is also facing increasingly severe environmental problems. "With the exposure of titanium dioxide pollution incidents, environmental policy tightening is expected to become more intense, more and more efforts to stop production for rectification, the adjustment of industrial structure upgrading is increasing." Well, general manager of the supermarket pigment Shanghai Cai Xu Bo said, " to the capacity is expected to achieve a certain degree. "

** Titanium mergers will accelerate the pace of restructuring **

It is reported that, "the titanium shaft dioxide industry access conditions" during the "Eleventh Five-Year" in order to "control the increment, optimize inventory," as the leading national industrial policy system titanium dioxide, an important part of the management and control policy.

Guo Xinrong said titanium dioxide industry is associated with the terms of the "titanium dioxide industry access" in "access" concept gives the height of new policies and requirements that enhance the "barriers to entry" restricted property "normative standard" adjustment of operational guidance and regulations.

In response, industry analysts believe that this will further promote domestic titanium dioxide pace of corporate mergers and acquisitions.

"According to the experience of other countries, titanium dioxide industry mergers and acquisitions is the trend towards centralization in the next 5 to 10 years, mergers and acquisitions dioxide enterprises will become more frequent, domestic bound to occur 3 to 5 more than 300,000 tons titanium dioxide business. "Cai Xu Bo said," our titanium dioxide business is business model from extensive to intensive, intensive manufacturing operations paradigm shift. "

He is expected, with environmental upgrades, titanium dioxide industry and the US and Europe is bound to go through the same process of production, increase the proportion of the birth of industry upgrading chlorination, industry concentration increase, leading enterprises have the right to speak to gradually appear.

Deng Jie Beijing Oriental Horizon Technology Development Co., Ltd., general manager also held the same view. In his view, from the formal point of view, there is potential for 15-20 furniture manufacturers will gradually formed; and from the scale, will give rise to the leading multinational and Chinese industrial cluster shape, size and form of titanium dioxide chloride process more than 100,000 tons production.

China Titanium Association expects substantial growth in demand for short-term is difficult

SMM News: Great Wisdom AAStocks Newswires November 12 hearing, China has become the world's largest titanium producer and consumer countries, and China Coating Industry Association branch chairman Xie Xiangyun titanium dioxide industry is expected on the 12th, in the short term China Titanium demand will not grow larger.

In recent years, the domestic market, titanium pipe price dioxide, titanium dioxide, a significant slowdown in the growth rate of apparent demand trend. Supermarkets General Manager of good pigment Shanghai Cai Xu Bo said that 2013 years of the GDP growth rate has been below 8 percent, sluggish domestic demand for titanium dioxide.

Figure 1: 2008-2012 dioxide apparent demand for our

Cai Xu Bo said that, overall, the domestic titanium dioxide production growth slowing down, in 2012 the national production of 1.89 million tons of titanium dioxide, an increase of 4 percent in 2011, growth is slowing down; and from January to September 2013 by the prices down dragged down by sluggish sales, capacity utilization declined, the actual production of titanium dioxide by about 1.2 million tons.

Figure 2: 2003-2013 domestic titanium tube supplier dioxide production statistics (2013 annual production is estimated at about 1.8 million tons)

Xiexiang Yun said, according to the statistical analysis of the relevant marketing agency, this titanium dioxide business operating rate of about 66% capacity utilization rate of 95% titanium business, slag business started around 35%, this year there are more than 20% of earnings, the Other titanium dioxide business enterprises are very difficult.

"The central government's new term economic roadmap see steady growth, structural adjustment, to the way the main tone of China's economic development in the future and in the coming years." Xie Xiangyun that the next government will reduce the size of loans, land targets, production quantities can administrative and other direct interventions, and the main use of monetary, fiscal and other means of improving macroeconomic total. While the focus on adjusting the focus of market regulation, reducing the industry into the pre-examination and approval, to enhance the quality, safety, environmental protection, energy, technology and other aspects of the standard first-line supervision.

"The aim is to deepen market-oriented reforms had to build an upgraded version of the Chinese economy, and therefore impossible to have a massive investment stimulus policies." Xiexiang Yun said, "Titanium demand is expected in the short term there will be a big increase."

Accuracy, conditions and proper cutting parameters

The tool axial and radial runout accuracy is also important. For example, if the blade is not correctly installed in the cutter, the cutter around the cutting edge will quickly damage. When cutting titanium bar for sale, a number of other factors, such as poor tool manufacturing tolerances, wear and tool damage, the handle has a defective or poor quality, spindle wear, etc., will largely affect the tool life. Observations show that in all cases the processing underperforming, 80% are caused by these factors. Although most people prefer the positive geometry tool, but in fact slightly negative rake angle geometry of the tool can be removed with higher feed materials and feed per tooth of up to 0.5mm. But this also means that you must maintain optimal steady state, that the machine should be very strong, and the fixture should be extremely stable.

In addition to the Plunge milling (preferably circular blade) outside, you should try to avoid using 90 main angle, this usually helps to improve the stability and overall performance obtained, when used in shallow depths cut especially in the case, in When deep cavity milling, a recommended practice is to use the tool connected to the handle variable-length tool, rather than using a single length of the long knives in the whole process.

Adjustment of the cutting parameters to overcome lower vibration due to the amount of feed per tooth caused by traditional solution, but this method is not appropriate because it would have catastrophic cutting tool life and influence. Indexable insert cutting edges require a certain amount of rounding to increase the cutting edge strength and better coating adhesion.

When milling titanium bars, at least to the minimum required for tool feed amount of work - usually each tooth 0.1mm. If you throw vibration trend, the blade is damaged or shorten tool life issues will be inevitable. Possible solutions include accurate calculation of the amount of feed per tooth, and make sure it is at least 0.1mm.

It may also be lower spindle speed, in order to achieve the initial feed rate. If you use the smallest amount of feed per tooth, and the spindle speed is not correct, then the impact on the tool life can be as high as 95%. Lower spindle speed usually improves tool life.

Once established stable condition, can be a corresponding increase in spindle speed and feed rate to get the best performance. Another approach is to remove some of the blade from the cutter blade or select containing less cutter.

Titanium pipe in water purification Role

The main characteristics of titanium tubes for desalination:
Density, specific strength (strength / specific gravity) is high density metallic titanium 4.51g / cm3, higher than Al and less than steel, copper, nickel. The intensity ratio of the first metal but is located, is a stainless steel three times, 1.3 times the aluminum alloy;
Good corrosion resistance ) Titanium is a very reactive metal, which is very low equilibrium potential, thermodynamic corrosion tendency in the medium is large. But in fact the titanium is very stable in many media, such as titanium alloy plate in an oxidizing, neutral or weakly reducing medium such as corrosion resistant. This is because the titanium and has a great affinity for oxygen, air or oxygen-containing medium, the titanium surface layer of dense, strong adhesion, large inert oxide film to protect the titanium substrate corrosion. Even due to mechanical wear and tear will heal or regenerate quickly. This shows that titanium is a metal with a strong passive tendencies. Medium temperature below 315 ℃ titanium oxide film 3 is always kept this characteristic, a good heat transfer performance of metallic medical titanium plate, although lower than the thermal conductivity of carbon steel and copper, but the titanium excellent in corrosion resistance, so the wall thickness can be greatly thinned , and the surface of the heat exchanger and steam condensation droplets way, reducing the thermal group, so the surface is not scaling may also reduce the thermal resistance of titanium so that the heat transfer performance improved significantly

4 good heat resistance
The new long-term use titanium spring wire or higher temperature 600 ℃.
Good chemical resistance, low temperature performance as the representative of cryogenic titanium alloy, its strength with decreasing temperature increase, but the plastic change is not large.
Tensile yield strength of its performance close to that of titanium shows its yield ratio (tensile / yield strength) high, indicating that the titanium material difference in molding plastic deformation. Since the ratio of the yield limit of the titanium and the elastic modulus is large, so that resiliency titanium molding large.

The difference between titanium and titanium alloy plates

Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃. Titanium has good salt tolerance classes, the ability to seawater and nitric acid corrosion, Ti-30M alloy is resistant to high concentrations of hydrochloric acid and sulfuric acid corrosion. These advantages of titanium, grade 2 titanium wire deserved to be called a "space" metal, "Ocean" and the following metal steel, aluminum metal after the third and so on.
Titanium and titanium alloy material at room temperature forming plant, due to the forming force, a small amount of deformation limit and great resilience, which gave the manufacturing process brings a lot of difficulties, especially resilient, so that the hand injury the entire amount of labor large batch production can not meet the requirements.
The hot press forming is generally used in the manufacture of seamless titanium tube metal pieces and effective process methods, this method can be at room temperature (or heated state F) molded item, reheat Shaping: pull the materials can be directly used to form a heat and Hot school shape. Whether it is hot forming and heat were collapsed to form the school principle creep and relaxation of effort.
Thermoforming mainly take advantage of the softening and creep properties of the material in a heated state, and to improve the plastic to reduce and improve the molding forming force than to avoid cracking, but also reduce some rebound. Thermal Shaping mainly using the principle of stress relaxation in the heated state, in order to eliminate the springback, solve the problem of the precision of the parts due to the problems caused by springback.
In order to understand the mechanism of heat and hot forming shaped school must master creep and stress relaxation of principle. Month away, but this rationale Mrs perish only the right to development, but more with ten design chemical, atomic, gas and gas turbine boil, supersonic aircraft, spacecraft and other buildings of the structure of the product.
Titanium and its alloys as popular as the reason for the absence of aluminum, mainly due to high prices. To reduce costs, the new process for anyone conducting research abroad titanium alloys, such as electrolysis and direct reduction method, once the breakthrough will significantly decrease the cost of titanium sponge, will greatly stimulate the development of titanium grade 2 industry, we can only trace of such studies , can ensure China's titanium industry invincible. Besides the lack of significant capital investment in the processing of titanium and its alloys and titanium forming technology processing technology and applications, thus limiting the vigorous development of titanium industry.

Application material titanium and titanium alloys in medical titanium implants

Titanium is a chemically active element, which is easy to form a protective surface oxide film is a dense, this layer of oxide is insoluble, can effectively prevent corrosion of the metal continues. Titanium unlike other metals, it has several features:
- Low density of only 4.5g / cm3;
- Low thermal conductivity 22w / mk (low thermal conductivity);
- Good bearing capacity;
- High stability, alloying can improve performance;
- Outstanding corrosion resistance, and appropriate application of the general media and biological stability.
Titanium and grade 2 titanium alloy implants in medicine began in 1969, was mainly used to repair teeth. After 40 years of research and development, titanium has become one of the most widely used material in the oral implant disciplines, and titanium-based materials are also other tissues and organs in the human body is used instead.
After implantation, several replacement parts to be used in conjunction with the body's adjustment. By adjusting the shape of the implant surface to achieve engagement with the bone surface of the implant, the desired effect can be achieved in a few years. In the General Assembly of the International Association for Dental Research 86th session held recently, the Swedish researchers spoke of a "nano-structures", it is more than a hundred times smaller Canadian coins. Organizations can use this alternative can be achieved in four weeks after implantation of good bone and dental implants combined effect of substance.
By adjusting the size and position of the implant surface nano-organization, not only patients receive faster, more reliable treatment, but also to help people on the human body - implants transfer order in understanding the future of implant surface further study provides guidance.
